Integrate barcode recognition in your programs |
 |
OverviewQualitySoft offers a powerful software for barcode recognition from digital images or Adobe PDF-Documents. The images are produced using scanners, digital cameras or fax machines.
QS-Barcode SDK (Software Development Kit) was developed from algorithms in the QS-Beleg form recognition software, which has been used successfully for years. It recognizes the barcode symbologies Codabar, Code 2/5 interleaved, Code 2/5 Industry, Code 39, Code 39 extended, Code 32, Code 93, EAN 8, EAN 13, UPC a, UPC E, Code 11, Code 128 and EAN 128. We also support GS1 DataBar (POS) barcodes! New are various Post Codes like Royal Mail Barcode, Dutch Code KIX, Australian, Canadian CPC, Code One, Intelligent Mail Barcode IMB, PostBar, PostNet, Planet Code. The most common use of barcode recognition is quick and reliable identification and indexing of documents for data capture (OCR, ICR, etc.) and archiving.
Optionally you can receive two-dimensional barcode recognition: PDF417 barcode, Aztec Code, QR Code and Data Matrix (not only ECC200, but also ECC000-140). The complete character set and binary data can be encoded in two-dimensional barcodes, up to 3,000 characters.
The Data Matrix barcode was designed for small parts marking and is today used for small electrical parts, by the pharmaceutical industry for unit dose packaging, by the automotive industry and by NASA.
Scanning
Scanning in this area is usually done with 200 or 300 dpi resolution. In order to get a correct barcode reading at such a low resolution, the barcodes must be printed clearly and they must not be positioned too closely .We recommend a maximum of 2 characters/cm at 200 dpi and a maximum of 3 characters/cm at 300 dpi. For example, an 8-digit barcode should have a width of 4 cm to be read properly at 200dpi.
The PDF417 requires a higher resolution. For error free recognition, the minimal module width must not be under 5 pixels.
In addition to scanner resolution and barcode width, reliable recognition also depends on other factors:
barcode symbology scanner preferences height of barcode skew angle (particularly with sticky labels) quality of printer and paperQS-Barcode SDK offers several parameters to make the recognition quality more reliable in terms of basic requirements. Before QS-Barcode is used in daily routine, it is highly recommended to perform a larger test using the suggested barcode under regular production conditions.
Please send your questions and test images to support@qualitysoft.de. We are always happy to help you!
ShipmentQS-Barcode SDK software comes as a developer library (C-Lib, DLL and OCX) for Microsoft Windows (look here for Windows CE). The product is designed for developers who wish to integrate barcode recognition functionality into their own programs. Integrating functionality is easy and performed quickly. Following parameter setting (symbology, position of the barcodes), the image is transferred to the library and the recognition function is called up. The result structure provides the recognized results and additional information about the barcodes. Please find interface details in our download area. In addition to the library, QS-Barcode SDK also comes with test application and code examples on library integration.
